ubnt EdgeSwitch 24-Port 250W DHCP_CLI[osapiTimer]: dhcp_prot.c(812) 1285780 %% Failed to acquire an IP address on Network Port; DHCP Server did not respond.

查看EdgeSwitch日志: #show logging buffered | include dhcp

发现如下日志刷屏了:

DHCP_CLI[osapiTimer]: dhcp_prot.c(812) 1285780 %% Failed to acquire an IP address on Network Port; DHCP Server did not respond.

找了一下原因:

发现此交换机管理地址: EdgeSwitch默认设置为DHCP，因此它将尝试自动获取IP地址。如果获取失败，它将使用默认备用IP地址，192.168.1.2。

使用#network protocol none 将协议设置为空.然后交换机就不会再自动获取IP地址了,如果有需要,可以自己设置静态地址,做为管理地址.
